Definitions
- the present invention relates to a sliding member used in a bearing which slidably bears a shaft.
- any sliding materials in which a Cu-Sn alloy is bounded to a copper plated backing plate of steel have been often used.
- the sliding materials in which the Cu-Sn alloy is bounded to the copper plated backing plate of steel have been used for a sliding part using any oil.
- any sliding materials using resins have been used for a sliding part using no oil.
- the conventional sliding member using the resins is configured so that a porous layer made of Cu-Sn alloy is formed on the copper plated backing plate of steel and polytetrafluoroethylene (PTFE) is filled into the porous layer.
- PTFE polytetrafluoroethylene
- Such a sliding member into which the PTFE is filled may be used for a sliding member using the oil such as a shock absorber of a vehicle or the like.
- the conventional sliding member is configured to have a smoothing sliding surface.
- a technology in which any grooves for reserving a lubricant have been provided in a sliding surface thereof to supply the lubricant to the sliding surface has been proposed (For example, see Patent Document 1).
- a technology in which a holding surface of columnar or cylindrical object is subjected to knurling to keep the object from deflecting has been proposed (For example, see Patent Document 2)
- EP 1584828 A1 discloses a sliding bearing used under an oil-supplying circumference, and refers to a variation of the coefficient of friction of dynamic friction force as a peripheral speed is reduced r
- EP 1 412112 B1 discloses a self lubricating sliding bearing with a sintered porous sliding layer.
- the sliding member has been used as a guide bushing for guiding a piston rod which has reciprocated by transmitting thereto any operations of a suspension mechanism varied following a variation of a road surface or the like.
- the shock absorber damps any vibrations against an input from outside by using viscous damping of fluid.
- friction force occurring at the guide bushing for guiding the piston rod when reciprocating exerts any influence on any comfort of driving a vehicle or the like.
- a relationship between static friction force acting on when a stopped piston rod starts moving and dynamic friction force acting on when the piston rod moves exerts any influence on any comfort of driving a vehicle or the like.
- a shape of the sliding surface thereof or the like is fixed in order to decrease the friction force so that there is no sliding member that can control the relationship between the static friction force and the dynamic friction force.
- the invention has an object to present a sliding member that can control the relationship between the static friction force and the dynamic friction force.
- the invention relates to a sliding member comprising a metal substrate and a sliding layer that is configured by forming on a surface of the metal substrate, the sliding layer slidably bearing a slide member, the sliding layer including a porous layer made of Cu-Sn alloy on the surface of the metal substrate by sintering the sliding layer being made by filling a resin into the porous layer and sintering the resin, the sliding layer being formed as uneven surface halving projections to prevent an oil film by sliding_from being formed thereon, the projection being formed so that the dynamic friction force is made larger than a dynamic friction force when an oil film is formed, the dynamic friction force comes closer to the static friction force of the uneven surface and the rate of change in the dynamic friction force in relation to the static friction force is thus kept smaller, the uneven surface being formed on a cylinder-shaped internal circumferential surface thereof slidably bearing the slid member so as to have a projection including a point-like vertex or a line-like vertex.
- the uneven surface having projections to prevent an oil film from being formed on the sliding layer it is possible to make the dynamic friction force larger and keep the rate of change in the dynamic friction force in relation to the static friction force smaller. Further, it is possible to make the static friction force larger due to a shape of the uneven surface. This allows the comfort of driving a vehicle or the like to be improved when applying the sliding member according to the invention to the shock absorber.
- FIG. 1 is a perspective view of the sliding member according to an embodiment
- FIG. 2 is a sectional view of the sliding member according to the embodiment for showing an example of schematic organization thereof
- FIG. 3 is a perspective view of a sliding surface of the sliding member according to the embodiment showing an example thereof
- FIG. 4 is a sectional view of the sliding member according to the embodiment for showing a using example thereof.
- a sliding member 1 of the embodiment constitutes a bearing having a cylindrical shape as shown I FIG. 1 and an internal circumferential surface thereof is a sliding layer 2 along a shaft.
- the sliding member 1 is configured, as shown in FIG. 2 , by forming on a surface of a metal substrate 3 a porous layer 4 made of alloy material, filling the resin into the porous layer 4 and sintering the resin 5 so that the sliding layer 2 is formed.
- the sliding member 1 is provided with an uneven surface 6 on a surface of the sliding layer 2.
- the uneven surface 6 is provided with projections 6a having any optional shape in which line-like vertexes in each line of which the vertexes are continuous are arranged in gridlike fashion as shown in FIG. 3 , so that the formation of oil film can be controlled.
- the sliding member 1 is used as a sliding portion in a guide bushing 8 which guides a piston rod 7 reciprocating by transmitting thereto an operation of a suspension mechanism varied following any variations in a road surface, as shown in FIG. 4 .
- the sliding surface along the piston rod 7 is configured as the uneven surface 6 providing with the projections 6a shown in FIG. 3 , there is a line contact in the embodiment, not surface contact which causes an oil film to be formed between the sliding member and the piston rod 7 when sliding the piston rod 7.
- the uneven surface 6 is configured so to have a shape such that the projections 6a elongate toward an oblique direction in relation to a sliding direction of the piston rod 7.
- FIG. 5 is a graph showing a relationship between the static friction force and the dynamic friction force.
- a vertical axis indicates friction force (N) and a horizontal axis indicates a stroke (mm).
- the piston rod reciprocates based on that the suspension follows the variations or the like of the road surface. Based on a fact such that the piston rod reciprocates, there is a state where the piston rod stands still.
- the uneven surface 6 has larger static friction force Fs 1 than that of a case where the sliding surface along which the piston rod 7 contacts is smooth, based on orientation, numbers, dimension of the projections 6a and the depressions 6b. It is desirable that the uneven surface 6 has a shape such that the projections 6a elongate toward an oblique direction in relation to a sliding direction of the piston rod 7. Further, when the sliding surface along which the piston rod 7 contacts is smooth, the sliding of the piston rod 7 causes the oil film to be formed between the sliding surface and the piston rod 7 so that the dynamic friction force is lowered. On the other hand, the projections 6a are formed on the sliding surface along which the piston rod 7 contacts so that the oil film based on the sliding of the piston rod 7 is prevented from being formed.
- the dynamic friction force Fm 1 When the dynamic friction force Fm 1 is made larger, the dynamic friction force Fm 1 comes closer to the static friction force Fs 1 so that the rate of change in the dynamic friction force Fm 1 in relation to the static friction force Fs 1 is kept smaller. Further, since the guide bushing 8 is used in the oil, a lubricant quality thereof is maintained because the oil stands between the rod and the depressions 6b of the uneven surface 6.
- the sliding layer 2 in which the uneven surface 6 is formed on the sliding surface thereof is configured by PTFE as resin 5.
- PTFE has a coefficient of friction ⁇ 1 of about 0.1 while the oil used in the shock absorber has a coefficient of friction ⁇ 2 of about 0.01.In a state where the piston rod stands still, any oil film is not formed between the piston rod and the guide bushing and the static friction force Fs is influenced by the coefficient of friction ⁇ 1 of PTFE.
- the dynamic friction force Fm is influenced by the coefficient of friction ⁇ 2 of the oil so that the dynamic friction force Fm is lowered and the rate of change in the dynamic friction force Fm in relation to the static friction force Fs becomes larger.
- the projections 6a of the uneven surface 6 formed on the sliding surface along the piston rod 7 prevent any oil film from being formed when the piston rod 7 slides so that the dynamic friction force Fm 1 is also influenced by the coefficient of friction ⁇ 1 of PTFE and the rate of change in the dynamic friction force Fm 1 in relation to the static friction force Fs 1 is kept smaller.
- FIG. 6 is a diagram for showing a configuration of an example of a testing machine for measuring the static friction force and the dynamic friction force.
- a testing machine 10 the guide bushings 8 to be tested are mounted in bearing bases 11 and a load portion 12. Any traverse loads are applied to the load portion 12 through the guide bushing 8 between the bearing bases 11 bearing the rod 13 through the guide bushings 8. Friction force when vibrating the rod 13, to which the traverse load has been applied, by a vibrator, not shown, is measured by a load cell 14.
- a table 1 indicates results when measuring the static friction force Fs and the dynamic friction force Fm.
- each of the sliding members of the embodiment is configured so that the sliding layer 2 is constituted of the porous layer 4 made of metal material and the resin 5, as shown in FIG.
- the resin 5 being constituted of PTFE.
- the uneven surface 6 including the projections 6a is formed on the sliding surface which is a surface of the sliding layer 2.
- Each of the sliding members, not shown, of comparison example is configured so that the sliding layer is constituted of the porous layer made of metal material and the resin, the resin being constituted of PTFE. The sliding surface thereof is smooth.
- the sliding members of the embodiment forming the uneven surface 6 in the sliding surface keep the rate of change in the dynamic friction force Fm in relation to the static friction force Fs smaller than those of the sliding members of the comparison example having the smooth sliding surface.
- the similar results are given in all of the loads.
- FIGS. 7A and 7B are diagrams each for showing a relationship between dimensions of a projection and a depression in the uneven surface and the friction force.
- FIG. 7A schematically shows an example in which a space L1 between the projections 6a is about 0.1 mm.
- FIG. 7B schematically shows an example in which a space L2 between the projections 6a is about 0.06 mm.
- the sliding layer 2 is configured by the resin 5, in the embodiment, PTFE. Accordingly, when applying the traverse force F to the piston rod 7, the shape of sliding layer 2 is changed. Under the condition where the piston rod 7 stands still, a contact area thereof when changing the shape by the traverse force F remains unchanged as compared with a case of no load. Accordingly, the static friction force Fs 1 remains unchanged regardless of the dimensions of the projection and the depression in the uneven surface.
- adjacent projections 6a do not interfere with each other in a case where the space between the projections 6a is large, as shown in FIG. 7A , and an amount of change is large while the adjacent projections 6a interfere with each other in a case where the space between the projections 6a is small, as shown in FIG. 7B , and an amount of change is small. Accordingly, there is a tendency such that the larger the space between the projections 6a is, the larger the dynamic friction force Fm 1 is.
- the friction force can be controlled in addition to a function to guide the piston rod 7 by providing the sliding surface of the guide bushing 8 with the uneven surface. Further, it has been understood that regarding a dimensional relationship of the space between the projections 6a of the uneven surface 6, the larger space is good.
- the uneven surface 6 formed in the surface of the sliding layer 2 is not limited to the shape thereof shown in FIG. 3 :
- the shape thereof such that the projections 6a elongate in parallel with the sliding direction of the piston rod 7 may be configured, or the combination with the depressions having optional shapes such as a quadrangular pyramid shape, a triangular pyramid shape or circular cone shape may be configured.
- the combination with the projections having optional shapes such as a quadrangular pyramid shape, a triangular pyramid shape or circular cone shape may be configured.
- FIG. 8 is a perspective view of a sliding surface of the sliding member according to another embodiment.
- the uneven surface 6 may be configured by combining projections 6c each having a quadrangular pyramid shape with point-like vertex in order to prevent the oil film from being formed.
- the porous layer 4 made of Cu-Sn alloy is formed on a surface of the metal substrate 3, PTFE which is the resin filled into the porous layer 4 is sintered and the sliding layer 2 providing a surface thereof with the uneven surface 6 is formed.
- the present invention may be applied to a sliding member used under an oil-supplying circumference.
